Reload .ipynb notebook when the file changed

[szymonmaszke]

Is it possible for the notebook to autoreload currently opened file if it has been changed by some other software?

For example:

1. Start foo.ipynb from CLI using jupyter notebook foo.ipynb
2. Modify foo.ipynb JSON file and save it
3. Jupyter browser view updates after this event

Preferably without any confirmation popups etc. If it's impossible or requires jupyter's source code modification, than I would like to know whether I could send a signal to the kernel to refresh the page after editing the file?

Without a popup would be nice.

This functionality is necessary. when using jupytext, to edit the .md and auto update the paired .ipynb, then the notebook in the browser is updated automatically is very important and necessary. otherwise, it is very annoy manually refresh page when updating every time in .md.

This functionality would be great when paired with jupytext!

Maybe some day.

Is there any news on this? Autoreload is still missing after 5 years.
